After Transmigrating Into a Book, I Became the Darlings of the Powerful

Su Mian inexplicably transmigrated into a book, becoming a vase who had nothing going for her except her looks, a cannon fodder character among cannon fodder! Her adoptive mother's constant disdain, her adoptive father's suspicious intentions, and her adoptive sister's malicious suspicions made life at home a struggle. Just when things finally started looking up, her adoptive sister stole her identity. Using Su Mian's name, she moved into a wealthy family, dated the male lead, and had the male supporting character and the villain falling madly in love with her, going wild for her, and banging their heads against walls for her. Su Mian, meanwhile, had fewer than a thousand words of screen time, all of it spent providing the heroine with an identity. In the end, her adoptive parents handed her over to a punk, who abused her to death! Su Mian was shocked! Su Mian was stunned! Su Mian was completely dumbfounded! What the hell kind of brainless, shameless novel was this? To stay alive, Su Mian decided to change the plot. But before she could do anything... The powerful man A, who had originally been madly devoted to the heroine, said, “Just tell me what you want. If I can do it, I'll do it. If I can't, I'll still find a way.” The powerful man B, who had originally been unwavering in his love for the heroine, said, “If anyone lays a finger on you, I'll make them regret ever existing.” The powerful man C, who had originally been banging his head against a wall for the heroine, said, “Look at the brightest star in the sky. Doesn't it look like the tender way I gaze at you?” Su Mian: “...” Can't you guys stick to the plot? Weren't I supposed to be just cannon fodder? Powerful Men A, B, and C: “In our world, you're the only heroine!”
